I fully agree. When I’m drunk I can sleep through a lot, and I'm normally a very light sleeper. When I was a teenager, I was unwell and couldn’t sleep and it was the middle of the night. I was listening to music through my earphones and had just been changing songs so my eyes hadn’t accustomed to the pitch black darkness of my room. I felt someone grab my arm and my body went into total panic, in that second I started shaking, my heart felt like it dropped and I let out a noise which I can only describe as a horse neighing. I lit my phone up and it turned out to be my mum checking on me thank god but I was so surprised at my bodies reaction and the noise I made. I wouldn’t be surprised if there wasn’t much noise made by the victims during the attacks, if they woke they were probably in total shock
